Ventricular assist and support device
A ventricular assist device to provide cardiac assistance to a damaged ventricle chamber. The ventricular assist device is formed of an ventricle body which is anchorable to spaced ventricle wall portions to provide cardiac assistance. Operation of the ventricular assist device is timed or synchronized with the operating phases of the ventricle chamber. The ventricular assist device can be intravascularly deployed to provide a less invasive treatment procedure and can be adapted to provide static support if active assistance is no longer required.
1. A ventricular device comprising:
a first ventricle anchor and a second ventricle anchor anchorable to opposed ventricle wall portions; and
a ventricle body positioned entirely between the first ventricle anchor and the second ventricle anchor and extending between and terminating at the first ventricle anchor and the second ventricle anchor where the ventricle body includes a first body portion of fixed length extending from the first ventricle anchor and a second body portion of fixed length extending from the second ventricle anchor that is positioned in an extended configuration partially within a lumen of the first body portion, wherein a portion of the first body portion and a portion of the second body portion each are configured to extend through one of the opposed ventricle wall portions, and wherein the first body portion and the second body portion are slideable relative to one another to reversibly expand and collapse between a first length dimension and a second smaller dimension to provide cardiac assistance.
2. The ventricular device of claim 1 wherein the ventricle body includes the first body portion coupled to the first ventricle anchor of the opposed spaced ventricle anchors and the second body portion slidably coupled to the first body portion and coupled to the second ventricle anchor of the opposed spaced ventricle anchors to allow the ventricle body to reversibly expand and collapse between the first length dimension and the second smaller dimension.
3. The ventricular device of claim 2 and further comprising a cable coupled to the second body portion to slidably adjust the second body portion relative to the first body portion to reversibly expand and collapse the ventricle body between the first length dimension and the second smaller dimension.
4. The ventricular device of claim 1 and further comprising at least one ventricle plate coupled to an end portion of the ventricle body.
5. The ventricular device of claim 4 including a plurality of ventricle plates including a first ventricle plate coupled to one end portion of the ventricle body and a second ventricle plate coupled to an opposed end portion of the Ventricle body.
6. The ventricular device of claim 4 wherein the ventricle plate is generally “U” shaped and includes a first end coupled to one end portion of the Ventricle body and a second end coupled to an opposed end portion of the Ventricle body.
7. The ventricular device of claim 1 and further comprising an actuator assembly coupled to the Ventricle body to reversibly expand and collapse the ventricle body between the first length dimension and the second smaller dimension.
